Multi Constraint Shortest Path Routing

Shortest-Path Routing in Arbitrary Networks

We introduce an on-line protocol which routes any set of N packets along shortest paths with congestion C and dilation D through an arbitrary network in O(C +D+log N) steps, with high probability. This time bound is optimal up to the additive log N , and it has previously only been reached for bounded-degree leveled networks. Further, we show that the above bound holds also for random routing p...

Avoiding Ties in Shortest Path First Routing

First we discuss problems associated with ties and flow splitting with shortest path first protocols such as OSPF and IS-IS. The problems relate to uncertainty in the splitting when there are multiple shortest path from a source to a destination. Even if routers are configured for even splitting, there can easily be unpredicted biases that can overload links and thereby affect quality of servic...

Lower Bounds for Shortest Path Interval Routing

Interval Routing was introduced to reduce the size of the routing tables: a router nds the direction to forward a message by determining the interval that contains the destination address of the message, each interval being associated to one particular direction. In this paper, we give lower bounds for the minimum number of intervals per edge needed to achieve shortest path routings for the cla...

The Symmetric Shortest-Path Table Routing Conjecture

A symmetric shortest-path table routing is a set of paths between all pairs of nodes in a graph such that the set is closed under path reversal, each path is a shortest path in the graph, and all paths with the same destination form a tree with a sink at the destination. Such a routing can be found for any finite, connected, undirected, positiveweighted graph by “salting” the edge weights so th...
